Kim is designing a railway track. Each point on the railway track should be equidistant from the two roads shown below. Kim wrote the following steps to construct the railway track. Step Description 1 Adjust the compass to a medium width and place it at point B and draw an arc which cuts at point P and at point Q. 2 Adjust the compass to the width of and place it at point P and cut an arc. 3 Reduce the width of the compass and place it at point Q and draw an arc which intersects the previous arc at a point S. 4 Use a straightedge to connect the points B and S and extend it beyond S. Which is the first step that was done incorrectly? Step 1, because the compass should be placed at points A and D. Step 4, because the compass should be used to connect the points B and S. Step 3, because the width of the compass should not be changed. Step 2, because the width of the compass should not be so large
